Given humans' limited ability to recall past experiences for evaluation, scholars have proposed the peak-end rule stating that if perceived discomfort at the end of an aversive experience is lower than the peak discomfort experienced, the aversive experience will be remembered more positively. The purpose of this study was to evaluate the peak-end rule as applied to high-intensity interval exercise (HIIE). Participants were 30 inactive men ( age = 27.9, 5.2 years). In the first session they performed a graded exercise test on cycle-ergometer to determine their maximal aerobic power (MAP) ( = 233, = 35W); and, in the second and third sessions, they performed two HIIE protocols in randomized order: (a) Short trial - 20-minutes of HIIE, composed of 30-second efforts at 100% of MAP interspersed by 30-seconds of passive recovery; and (b) Long trial - 20-minutes of the short trial, plus 10-minutes more of HIIE, decreasing 3% of MAP in each additional bout, resulting in 70% of MAP in the last bout. During exercise, we recorded the participants' rating of perceived exertion (RPE) and affect, using the Feeling Scale (FS). At 30-minutes post-exercise, we again recorded the participants' affect, using the Global Affect Evaluation (GAE) and their session-RPE, and we recorded their enjoyment, using the Physical Activity Enjoyment Scale (PACES). In the last session, the participants chose a favorite protocol to repeat. All sessions were interspersed by at least 72 hours. The 10-minutes extra HIIE in the Long-trial condition resulted decreased heart rate values ( = 157, = 13bpm to = 144, = 14bpm; p < 0.001), but psychological responses during and after exercise did not differ, nor did participants' preferred HIIE protocol. As the load drop for the Long-trial was not enough to change the psychological responses during exercise, there was no difference in the retrospective evaluation as the peak-end rule would have suggested.
鉴于人类评估过去经历的能力有限，学者们提出了峰值结束规则，即如果在不愉快体验结束时的感知不适低于体验峰值时的不适，那么不愉快的体验将被更积极地记住。本研究旨在评估峰值结束规则在高强度间歇训练（HIIE）中的应用。参与者为 30 名不活跃的男性（年龄=27.9，5.2 岁）。在第一次会议上，他们在自行车测功仪上进行了分级运动测试，以确定他们的最大有氧能力（MAP）（=233，=35W）；在第二次和第三次会议上，他们以随机顺序进行了两项 HIIE 方案：（a）短试验-20 分钟的 HIIE，由 30 秒的 100%MAP 努力和 30 秒的被动恢复交替组成；（b）长试验-20 分钟的短试验，加上 10 分钟的 HIIE，每个额外回合减少 3%的 MAP，最后回合达到 70%的 MAP。在运动过程中，我们使用感觉量表（FS）记录参与者的感知用力（RPE）和情绪。运动后 30 分钟，我们再次使用全球情感评价（GAE）和他们的会话-RPE 记录参与者的情感，使用身体活动享受量表（PACES）记录他们的享受。在最后一次会议上，参与者选择一个喜欢的方案重复。所有会议之间至少间隔 72 小时。长试验条件下的 10 分钟额外 HIIE 导致心率值降低（=157，=13bpm 至=144，=14bpm；p<0.001），但运动中和运动后的心理反应没有差异，参与者也没有喜欢的 HIIE 方案。由于长试验的负荷下降不足以改变运动中的心理反应，因此根据峰值结束规则，回顾性评估没有差异。
